Ruin Ernshaw

My avatar randomly sticks while moving. It will continue walking or turning untill I log out. Also, during this time I cannot use the tabs at the top of my viewer. I have tried switching viewers but still have this problem. I recently bought a new laptop but it has only just started happening. The only thing I could think of, is that Ive just upgraded from Windows 8 to 10. Could this be the problem and if so, is there anything I can do about it? Help. Ruin Ernshaw
